User's Manual 58. Configuration Parameters Reference
Parameter Description
Max Reference Delay x10 msec
[AcousticEchoSuppMaxRefDela
yx10ms]
Defines the acoustic echo suppressor maximum reference delay
(in 10-ms units).
The valid range is 0 to 40. The default is 40 (i.e., 40 x 10 = 400
ms).
[ECHybridLoss]
Defines the four-wire to two-wire worst-case Hybrid loss, the ratio
between the signal level sent to the hybrid and the echo level
returning from the hybrid.
ï‚§ [0] = (Default) 6 dB
ï‚§ [1] = N/A
ï‚§ [2] = 0 dB
ï‚§ [3] = 3 dB
[ECNLPMode]
Defines the echo cancellation Non-Linear Processing (NLP) mode.
ï‚§ [0] = (Default) NLP adapts according to echo changes
ï‚§ [1] = Disables NLP
ï‚§ [2] = Silence output NLP
Note: The parameter can also be configured in a Tel Profile.
[EchoCancellerAggressiveNLP]
Enables the Aggressive NLP at the first 0.5 second of the call.
ï‚§ [0] = Disable
ï‚§ [1]
= (Default) Enable. The echo is removed only in the first half
of a second of the incoming IP signal.
Note: For the parameter to take effect, a device reset is required.
[RTPSIDCoeffNum]
Defines the number of spectral coefficients added to an SID
packet being sent according to RFC 3389.
The valid values are [0] (default), [4], [6], [8] and [10].
Answer Detector (AD) Parameters
Enable Answer Detector
[EnableAnswerDetector]
Currently, not supported.
Answer Detector Activity Delay
[AnswerDetectorActivityDelay]
Defines the time (in 100-msec resolution) between activating the
Answer Detector and the time that the detector actually starts to
operate.
The valid range is 0 to 1023. The default is 0.
Answer Detector Silence Time
[AnswerDetectorSilenceTime]
Currently, not supported.
Answer Detector Redirection
[AnswerDetectorRedirection]
Currently, not supported.
Answer Detector Sensitivity
[AnswerDetectorSensitivity]
Defines the Answer Detector sensitivity.
The range is 0 (most sensitive) to 2 (least sensitive). The default is
0.
